Lewis Hamilton showed his frustration with an exasperated radio message at the end of the final practice session in Bahrain on Saturday.
Hamilton and the rest of the grid were going through their final preparations in the morning practice session, before qualifying later in the day. It also provided one of the final opportunities for the driver to practice a standing start before the first race of the season on Sunday.
But the Brit never got the chance at the end of FP3. Mercedes had tried to send him out from the garage at the very end of the session so he could trundle around the track and practice on the start line, but they got their timing all wrong.
